CAR-DOOR-LOCKING DEVICE.

Application led January 12, 1922. Serial No. 528,652;

To all whom it may concern Be it known that I, YViLLrAM E. `W1Nn, a citizen of the United States of America, residing at Toledo, in the county of Lucas and State of Ohio'` have invented certain new and useful Improvements in Car-Door` Locking Devices, of which the following is' erably of a bracket in which is pivotally mounted a hook that is designed to engage a ledge secured to the bottom of the. door, and to provide means consisting of a partly removable member having an enlarged portion or head on its inner end that will tightly fit between the hook and a casing on the housing, and thereby prevent the accidental disengagement of the hook from the ledge of the door.

Still another object of the present invention is to provide a locking deviceA that is extremelyetticient in action, consisting of but two moving parts, one the hook, which is pivotally mounted on the bracket and the other the wedge member that is contained in a casing on the bracket, and valthough freely movable therein cannot be lost from the casing.

With these and other-objects in view, the invention consists in certain new and novel constructions and combination ofparts as will be hereinafter more fully described and pointed out in the claims.

Referring now to the drawings, showing a preferred embodiment of the invention Fig. 1 is a View in side elevation showing a fragmentary portion of a car, one side of a door` and the locking device supporting and 'locking the door in its closed position, a portion of the casing' being removed for sake of clearness.

Fig. 2 is a sectional view taken on line 2 2 of Fig. 1 looking in the direction of the arrows.

Referring now more in detail to the drawings, a fragmentary portion 1. of theside of a car is shown having a bracket 2 secured to the center sill (not shown) from which is hinged the door 3, that has secured to the bottom thereof the angle iron 4, that extends completely across the door and out beyond its free edges on both sides to form ledges that are to be engaged by hooks 5 mounted on the brackets 6, which brackets are secured to the side of the car body.

It will be understood that I have only shown one bracket and hook in the drawings, but 1n most instances a similar locking arrangement is used on the other side of thev door also, and a description of one will be a description of both.

The bracket 6 may be rectangular in shape and may be provided with the bosses 7 through which rivets 8 will be'passed to secure the bracket t0 the side of the car,

vwhile a plate 9 may be used on the inner side of the car opposite the ,lower bosses to provide a reinforcement for the locking devices, if desired.

Preferably formed integrally with the bracket 6 is the casing 10,which as will be seen, extends Vas at 11, above the upper edgel of the bracket, and is provided with the slot 12, through which extends the outer end of a wedge member '13, shortly to be described.-

An arcuate riblt is formed on the bracket i at the-topmost point of the casing l() to restrict the opening of the slot 12. rlhe width of the casing'l() is approximately twice the width of the shank of the hook 5 so that the hook may be free to swing rearwardly from disengagement with the ledge formed by the angle iron. Also formed at the bottom of this casing is a slot or opening between thel therebv holding the hook in its forward and locked position with relation to the door. The rib 15 in the lower slot'or opening prevents the wedge member 13 from dropping without the casing while the arcuate rib 14, at the topl of the casing` prevents the accidental removal of the wedge-shaped member from without the top of the casing.

The wedge member l?) is enter-able within the casing from the bottom when the hook member pulled upwardly and then out wardly until it assumes the position shown clearly in the dotted lines in Fig. 1.

In the present embodiment of the invention, have shown a bolt 19 as passing through the casing 10 and the bracket 6 and the upper end of the hook 5. which bolt also vextends through the side of the car body and is secured by the nut Q0, while the opening in the casing and the bracket is shown provided with the bossesv 21.

1t is to be understood, however, that other forms of pivotal support might be used rather than a bolt or nut. if desired.

Also, I have shown a rib 22 shown between the casing 10 and the bracket 6, and a small projecting lug E28. which is a continuation of the rear wall of the casing, both of which add strength to the device, and in a like manner further reinforcing or strengthening ribs may be used if found desirable or necessary.

The operation of the locking device is eX- ceedingly simple.

Presuming the door iS in its open position. the wedge-shaped member 13 will be resting on the lower vedge of the upper Slot 12while the enlarged head 17 will impinge against the arcuate rib 14. The door will then be raised so that the hook 5 will engage the angle iron 4 which will support and hold the door in its closed position after which the wedge-shaped member will be forced inwardly and downwardly so that the en larged head .17 will jam between the rear edge of the hook and the rear wall of the casing 10` and thus tightly hold the hook in its forward and locked position.

From the foregoing it will be seen that the locking device consists of but two moving parts. easily operated, and will tightly hold the door in its locked position until the handle of the wedge-shaped member 13 is grasped to withdraw the wedge-shaped member from its locking position within the casing.

Furthermore` the locking device is oneY that is relatively cheap to manufacture, efficient in service and relatively light and compact in nature,

Having thus described my invention. what I claim as new and desire to secure by Letters Patent is:

1. A locking device for drop doors comprising a bracket, a hook pivotally mounted on said bracket and adapted to engage a ledge of a door to support the same, a casing formed on said bracket partly enclosing said hook, and means carried within said casing for holding said hook in its forward and locked position, Said ,book-holding means being removable from the casing only upon removal of the said hook.

2. A locking device for drop doors comprising a bracket, a casing on said bracket and a hook pivotally mounted on said bracket and partly Within said casing, said casing open at its lower edge to permit the swinging of said hook, a locking means for said hook. carried within said casing and forming al wedge between the rear of said hook and the rear wall of said casing 4when in its locked position to therebyv hold the hook in its operative position in said casing.v

3. A locking device for drop doors comprising a bracket, a. casing formed on said bracket and a hook pivotally mounted in said casing, said casing beingfopen along its lower edge to permit the swinging movement of said hook` a loosely carried member in said casing having an enlarged head, said head abutting against the rear edge of said hook and the rear edge of said casing when in its operative position tothereby hold the hook in its locked position` and said member with the enlarged head adapted to be lifted upwardly to thereby unlock .said hook,
